Hello,
This is a modified motherboard cover, which changes the internal geometry a little bit, adds additional venting holes, but most importantly - creates a space for mounting a 90mm fan.
I glued the duct to the cover with glue, but the fan cover is mounted with snap joints so that it can be taken off if necessary.
I recommend printing the cover panel with a brim and supports, as the corners like to warp up even with PLA and the cable guides have steep overhangs (you can see in the picture how they look without supports lol)
It's the first model I've made myself, if you have any thoughts on what could be better or where I made a mistake, please let me know :)
The author remixed this model.
